每个单位都采用规定色谱的扎带绕带100对及以上电缆加有1%的备用线对,但最多不超过10对;8.缆芯包带:缆芯外包覆非吸湿性、非吸油性的绝缘带;9.电缆屏蔽:用轧纹(或不轧纹)双面涂塑铝带纵包于缆芯包带之外,两边搭接粘合;10.电缆护套:黑色低密度、中密度或高密度聚乙烯;11.识别标记:电缆外表面打印。
例如,常用的线直径为24AWG的线径约为0.5mm(0.2mm2),26AWG,约为0.4mm(0.13mm2),AWG数值越大线径越小,平方越小。如果传输距离达不到以上数字,除了布线环境干扰恶劣外,那就是电缆的质量问题。

上述动作反复进行,电机转子就能继续转动。从以上单相步进电机的运行原理看出,单相步进电机的电磁转矩只在定子电流变换时产生,故其平均转矩比两相以上的电机要小得多,响应脉冲频率也在100pps以下,故其用途受到很大限制,只能在响应脉冲频率比较低的轻载下运行。时钟、车用计时器(发动机计时器)、水表计数器等。下图为另一种单相步进电机结构的照片,最左边为电机整机,其次为电机线圈,再次为定子铁心,最后是永磁转子。

作为电工,必须掌握一些最基本的概念和名词,比如,"线电压"、"相电压"。那么,什么线电压?什么是相电压?它们有什么关系?又有什么区别?想必很多初学者一头雾水。线电压:相线与相线之间的电压,比如,C三相,A相与B相之间电压,A相与C相之间电压,B相与C相之间电压就是线电压。也就是我们平时工作中说的"相间电压"。线电压和相电压相电压:是指三相电源或三相负载每一相两端的电压。三相四线制供电网中,每相火线和零线之间电压就是相电压。
